Abstract

The methods of radiologic investigation of the urinary tract have radically altered. Sonography has established itself as the basic method of demonstrating the size and shape of the kidney. Ultrasound reliably identifies cysts among renal tumors. It is increasingly used as the primary method in the search for nephrolithiasis or ureteral stones. Urography offers the highest resolution for the delineation of pathologic changes in the renal pelvis. It is no longer available as a screening method in suspected renovascular hypertension. CT serves to clarify doubtful sonographic renal findings. It is the method of choice for staging of renal tumors and the definition of parenchymal as well as perirenal damage after trauma. Angiography, especially as regards the diagnostic value of digital subtraction angiography, is the diagnostic method of choice in suspected renovascular hypertension. The diagnostic value of magnetic resonance imaging in nephrology and urology cannot yet be finally assessed.

Transhepatic vascular access for diagnostic and interventional procedures: techniques, outcome, and complications.

Early or multiple cardiac catheterizations may result in occlusion of the femoral veins prohibiting their use. The internal jugular or sub-clavian approach may be an appropriate alternative. However, these approaches may not be suitable in patients with surgical interruption of the superior vena cava. In other patients, they may not allow easy access to certain areas of the heart. The transhepatic approach is an important alternative route for performing cardiac catheterization and interventions. Depending on the planned procedure, it may be the preferred route to perform the cardiac catheterization even in the presence of patent femoral veins. The indications, technical details and potential complications of this approach are discussed.

Embolization for a bleeding pelvic fracture in a patient with persistent sciatic artery.

Emergency embolization for a bleeding pelvic fracture was performed in a patient with persistent sciatic artery, a rare anatomic variation in which the internal iliac artery continues to the popliteal artery. Successful hemostasis was achieved without complications by means of selective catheterization into each branch of the internal iliac artery. Awareness of this unusual vascular anatomy is critically important to avoid serious complication of emergency embolization.
